[24/Aug/2007:18:47:45 +0700] "GET http://74.125.15.24/get_video?
HTTP/1.1" 200 1176075 TCP_MISS:DIRECT
then i refresh page by press F5
[24/Aug/2007:18:48:15 +0700] "GET http://74.125.15.24/get_video?
HTTP/1.1" 200 1176075 TCP_MISS:DIRECT
any clue ?
Turning off strip_query_terms and turning on log_mime_hdrs showed the
following response headers in access.log (for
http://74.125.15.33/get_video?video_id=FJug16NlqPk):
HTTP/1.1 200 OK

They are serious about making sure this content is not cached.
